Morphology
Euphorbia + esula
This is a Latin binomial: the genus name 'Euphorbia' signals it is a plant (so a learner who knows that would infer a plant species), but the species epithet 'esula' is an arbitrary Latin label and carries no obvious English meaning. Therefore a learner could tell it is a Euphorbia species but could not derive the specific sense 'leafy spurge' or its weed status from the parts alone.
Etymology
Euphorbia esula may come from a Greek doctor named Euphorbus, who used plants with a white, milky sap for medicine, so many plants called Euphorbia have that sap. The second name esula was an old word for a kind of 'spurge', so the full name points to a milky-sapped 'spurge' and explains why this spreading 'weed' is called leafy spurge.
